IMPROVEMENT IN BOOK-COVERS.

Specification forming part of Letters Patent No. 210,193, dated November 26,1878; application filed April 4, 1878.

To all whom it may concern.-

Be it known that I, JOSEPH E. FARGO, of Lake Mills, in the county of J eflcrson and State of Wisconsin, have. invented a new and useful Improvement in Book-Covers, of which the following is a specification:

ened to the metal adheres very indifferently.

The object of my invention is to produce a spring-back for bOOkfrCOVGI'S, which will have a convex bearing-surface to prevent cutting the binding-cloth, and also a space, to receive suitable material to form a base, to which the binding-cloth, in part, is glued or otherwise attached.

The invention consists of a spring-wire bent in conformity to the outline of the back of the book. The intervening space is filled with pasteboard, 'cut and bent to the form of the back of the book, the whole being covered with cloth and glued to the pasteboard. By this means both the inside and outside are furnished with a textile surface, to which the finishing material will adhere.

Figure 1 is a perspective view, in which A A represent the book-cover; and B B, a

spring-wine, which is more clearly shown in Fig. 3.

In Fig. 2 the spring is shown as having its intermediate space filled with pasteboard and the whole covered with cloth 0 0, thereby being made ready to enter into and form a component part of the cover.

The ends e e of the spring are expanded, in order that the book may be easily entered and slid into its place. The sides of the spring approach each other till the center f f is reached, so that books of varying thickness may be introduced and firmly held.

This spring may be made of any elastic material, such as steel or brass wire, bent into the proper shape or form, and have its ends united by welding, soldering, or other suitable means.

I claim as my invention The spring-back herein described, consisting of a single wire having bearing-bars diverging from each other toward their ends and bent to form the semicircular portions, substantially as described, and for the purpose setforth.

JOSEPH E. FARGO.
